USB-RS232-PCB Rev 2
Figure 4.1 USB-RS232-PCB Pin Out (Top is TOP View, Bottom is BOTTOM View)
Changes made from Rev1 to Rev 2 design:
- Pad designation changed between Rev1 and Rev2 (see Figure 4.1)
- R1 doesn’t exist in Rev2 design, the selection of power signal is done using either R2 (+3.3V) or
R3 (+5V), (see Table 4.2)
- The LEDTX, LEDRX, PWREN and SLEEP are connected to the FT232R differently (see schematic)
The mechanical details of the PCB are shown in the following diagram Figure 4.2
